WILLIAM W. BATGHELDER, OF NEW YORK, N. Y.

CONSTRUCTION OF VAPOR-LAMP BURNERS.

Specification of Letters Patent No. 25,799, dated October 18, 1859.

To all whom it may concern:

Be it known that I, WV. W. BATOHELDER, of New York, in the county of New York and State of New York, have invented certain Improvements in Burners for Vapor of Oil of Turpentine and Analogous Liquids; and that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which Figure 1 is a perspective view of the burner from behind; Fig. 2 a perspective view of the retort and heating jet in an inverted position; Fig. 3 a section through the middle of the retort and escape pipe; Fig. 4 an elevation of the fountain and supply pipe.

My invention consists in certain improvements in the construction of burners for oil of turpentine and analogous liquids de scribed as follows. The fountain or reservoir aand supply pipe 6, containing the usual wick packing within, are constructed and operated in the same manner as in other vapor burners. At that part of the pipe 6 which I call the retort designated by letter 0 where the heat is applied for volatilizing the oil the passage turns at right angles and the vapor issuing from orifices i passes horizontally through the atmosphere into the vapor or gas pipe (Z, carrying with it a portion of air to commingle with the vapor. This pipe curves around nearly in circular form until it rises in a straight portion k, to form the jet m for burning the vapor. At a short distance, about quarter of an inch below the retort c which is connected with pipe is, this pipe is pierced or tapped and a small aperture a, made, to allow a small portion of the gas to escape the burning of which is to supply heat to vaporize the liquid in the retort 0. Connected with the bottom of the retort are two wire staples a, a the staple a nearest the pipe in, being somewhat longer than staple a The heating jet of gas from aperture 07. plays within the staples and there impinges upon the bottom of the retort and volatilizes the oil, the vapor of which issues in a stream from orifice 2'. The aperture 71. is slightly inclined so as to give direction to the flame against the bottom of the retort. This flame plays as a blue flame along the bottom of the retort through the farthest staple a as shown in Fi 2. If the staples be removed the jet of gas from n will burn with an ordinary white or yellow flame with smoke and the deposit of carbon upon the retort will intercept the heat so as to prevent the vaporization. The effect of the staples upon the flame is to reduce it at once to a blue flame without smoke and thus admit of its full heating power upon the retort. If the first of the staples a be removed the flame will smoke, or if they are not properly adjusted to the flame. The parts in the drawings are represented as somewhat near the actual size and relation for successful operation. If the flame be made to pass between two wires not bent in the staple form the blue flame will be produced and other forms may exert the same modifying influences upon the flame, but the most advantageous form in all respects is the staple form as shown in the drawing. As the gas issues from the pipe 70 after the commixture with air it is in a condition for perfect combustion under the retort and within the influence of the staples. I thus attain a long clear blue flame under the retort producing great heat and consequently a better light than where the heat is derived from the burning gas or vapor after it issues from the jet m.

It is well known that where heaters are used near to or in contact with the illuminating flame of lamps or gas jets, they not only intercept light but that they diminish the light very materially by their cooling influence. These difficulties I avoid entirely by the use of the small jet upon the retort in the manner above described.

That I claim as my invention is- 1. Modifying the flame under the retort by means of the wires 64, a or their equivalents in such manner that the deposit of carbon shall be prevented and the blue flame produced as hereinset forth.

2. I claim deriving the gas for heating the retort from the gas pipe cl, after its commiXture with air and before it reaches the illuminating et m by means of the aperture 07., as set forth.
